FOLDING PICTURE PUZZLE Filed Jan. 10, 1942 6 Sheets-Sheet 6 HAROLD EDBORG INVENTOR ATTORNEY Patented Aug; 24, 1943 Hattie niibcr gonieagc, 1 1.,meal-105mmbeck Press, IncQlVIoline, IlL, a'c'orp'orati'on of 'lliil'icis Application January '10, 1942,"Serial No. 426,307 I cocaine (@1273-155) The present invention relatesto an amusement device in the form of a ioldable flexible'sheet constituting a puzzle. -'Ihe-principal ebject of this invention is' to furnish amusement to those who takepleasure in solving puzzles; -It-is {my Wish to furnish a -puzzle ofthe type-indieated in which dissectedpicturesmay be printed upon or secured to adjoining triangles in which whe'n the flexible sheet is fiattened out, -there will not-be-a complete picture of any object but,-when-the sheet is folded properly,- a picture of any one of- 'two or more objects may be displayed'. 1

I --In*the drawings annexed hereto and forming a part thereof, there i is shown apuzzle inwhich heads of two animals maybe formedbyproperly folding the flexible sheet.- yIn these drawings;'

Fig. -1 shows one face of the' fleXible sheet-and Fig. 2 shows the opposite face thereof; a Figs. 3, 4, and'S shOW-One mode 'of -toldingthe sheet to produce the-pieture-ofa horse' s head,

while #FigJ-G shows the completed picture; r It Figs. 7, 8, and 9 show another mode of folding 1 the flexible sheet, and this results in the pro'duction of the picture of a cows' head; and

Fig. 10 shows the completedpicture ofthe.

T In another form of this invention, comprising the same number of triangles arranged in the same way but with part of. the triangles'separated from neighboring triangles in a difierent way, .a

fleXiblet-sheet may be .foldedsoas to= show'ipicr torial representations of the headsfof "four difierent animals; Itis of course understoodzthatthe I1 L 1 pictures are not necessarilythose of-animal heads but may represent any desired objects'lforthe sake ofuvariety. However; for the sakeiofrease. of

explanation, :the present form has: been selected to'illustrate'thispuzzle. Also, for the sakelafof ease of 'explanationfthe cli-fierenttriang-les have sheet being numbered from l to 16,, inclusive, while those'o-n theoppositeuiace are numbered f1'om-17-to32; inclusive. I-

It willi'be'noted that in each Iof'E'igs. I andZ, part 'ofl'the segments-illustrate part -of a cows head and part of them illustratepa'rts oira horsers head, but no group ofiadjacent segments illustrate a complete head ofany animaL inthe'ples- 'been numbered, those on'one face'of the flexible n50. ent instance; either a cow ona" horse. However, a a by; properly folding the flexible"sheetpsegments canbe brought into juxtaposition so that either a "complete horses head will be shown or} a complete cow?s head. t There are various solutions to r this cpuzzle *but the best method of solving it seems to be to make a list of all the triangles showing part of the horses head and-allsshowing part of'the'cowshead, and then fromathe'se'lists pick out the particular triangles representing particular. parts of each' head.

of the 'horses head, while triangles-- I, 2, :5; 6, 1,

show partsiofthe' cows head. vNo'w let-.us name the. parts of the horses head as -ears,: nose, 10Wer .jaw' and'sback 'ofn'eck, while the triangles illustrating these various parts are as follows:

"Ears -"a, 1 n; 22; 2s

Nose 3,15; 19 Jaw 4, 9',fl3,2'l Neck-| 2," H 15 29 Dividing-*the 'cows head ini thez'same' way'and calling the parts horns;.nose, jaw; and neck,'the triangles illustrating these Ivarious parts" are as .Now'letzus suppose'that we-wish tosolve this :puzzlelto get a picture of thehorsesihea'd. We

notice thatthree parts of the ho-rsesfliead are shown on each: of four triangles; while the nose is shown .on only three. I'Logically, "thenywe would select the horses nose as a foundationiipon which to build. 'I'herefore,we' would selectzeither triangle 3; triangle 1 I5; or triangle I 9, and-try to iold'the' puzzle so thatothen parts will comeinto vposition so that'wve would-get'a complete picture of the horses; head. If we start withtrianglefl, we can solve this by' folding-so thattriang-les i 4,11, and 23 are u-porso'that-triangles 3 LL23, and 21;-are'up,-; ei ther combinationi giving us-a complete -horses-head. If the faceshownimFig, l is up;

wean fold mangles 9 to Hi, inclusive, down around the vertical center line. ;Now, we will foldtriang-les 5 to 8; inclusive; d Wm-and then. fold triangle lup,

This produces the combination-3',4,- l'l, and1'23, which i a complete horses head;

Selectingtriangle :3 a as a starting: point; we might: solve this by turningtriangle. I up';;-9,:to l2, 1 l4, and l idown; :1 Sup, -6, -1,;-and '28'jup, :angl 29 .and-32-down'. Now; the triangles Pleftshowingare numbered}, H, 23, and 21,

which constitutea completehors'eshead.

If, instead of starting to build upon triangle 3, we would select triangle [5, we could solve the puzzle by turning triangles H to 20 and 25 to 28 up. Of course, this assumes that the face of the puzzle shown in Fig. 2 is up. Following this first step, we turn triangles l4 and I up, 25 up, I I up, and l3, I6, 30, and 3! down. We now have triangles 9, l5, l1, and 23 up, thus disclosing a complete horses head. Doubtless various other modes of folding this puzzle are possible which will result in the showing of the horses head.

Essentially, Figs. 3, 4-, and 5 illustrate the first solution given above. In Fig. 3, the right half'of the sheet is shown as being folded down or away from the observer. Fig. ashows this fold completed and triangle I started on its way to being folded over on triangle 2. Fig. 5 shows this fold completed and the lower half of Fig. 4 started toward being folded under to get it out of sight. When this fold is completed, we have what is shown in Fig. 6, namely, the complete horses head. ;I

Following the above method to solve for the cows head, we might use the number 31 as our base number on which to build, since there are only three triangles which show the cows nose, while four or five triangles show ach of the other parts of the head. We now fold triangle 3| down and then fold the lower rightihand half of the puzzle up along the diagonal line. Next we fold down along the vertical and horizontal lines the triangles at the right of and below the cows head.

1. A picture puzzle comprising a square sheet provided with medial fold lines dividing the sheet into squares, each of said squares being provided with a pair of diagonal fold lines, said sheet being I foldable in either direction on each of said fold lines, one of said squares being cut in two along the diagonal from the corner of the sheet to the center thereof, an adjacent square being out along the diagonal from the corner of the sheet to the center of the square, and the remaining two squares being cut from the edges of the sheet at the ends of the medial fold lines dividing said We now have a complete picture of the cows 7 head. I

As shown in Figs. '7, 8, and 9, this puzzle may be solved as follows: First the lower right hand half of the puzzl is turned up along the diagonal. Next, the lower triangle, comprising triangles 5 and 8, is turned up along the horizontal line. The next move is then to turn up the right hand triangle, comprising triangles 9 and 10, along the vertical line and follow this by turningtriangle H and the one below it, numbered l3, up along the diagonal line, thus placing triangles 9 and I0 over triangle 3. Thus we have triangles 2, 6, l, and Ill exposed, showing the completed cows head. f

By other solutions, we can form the cows head by exposing triangles I, -2, 6, and 3| or 2, v6, I, and 3|; or 6, I, I8, and 3|; or 2, I, I0, and [4; or I, 2, l0, and I4. Doubtless othersolutions can be found, and the search to find. the greatest number of solutions possible adds zest to the working of this puzzle. q

Another embodiment of this puzzle showsdissected pictures of four objects which may be animal heads, complete animals, or any other objects which the publisher of the puzzle may wish to substitute for those in the embodiment of the puzzle'which I have'worked out. In this embodiment of the puzzle, there are sixteen triangles, just as illustrated in the present drawings, the incisions being made in the same way as shown in Fig. 2 and as illustrated by the doublediagonal remaining two squares from the first two squares, the last mentioned cuts extending from their origins at the edges of the sheet along the diagonals of the said remaining two squares to the lines, said sheet being foldable in eitherdirection on each of said fold lines, one of said quadrants being out in two along the diagonal from the corner of the sheet to the center thereof, an adjacent I quadrant being cut along the diagonal fromthe corner of the sheet to the centerof the quadrant, and the remaining two quadrants being cut from the edges of the sheet at the ends of. the medial fold lines dividing said remaining-two quadrants from the first two quadrants, the last mentionedcuts extending from their origins at the edges of i the sheet alongthe diagonals of the said remaining two quadrants to the center thereof, said fold and cut lines dividing said sheet into segments, said segments having thereon partial representations of a known object, most of the adjacentsegments, when in non-folded position. showing non- .adjacent portions of the object, but theexposed face of the sheet, when properly folded, showing a representation of said known object.

3. A rectangular sheet, its two dimensions .be-' ing multiples of a common denominator of length, said sheet being foldable along fold lines parallel .to" the edges of the sheet and spaced therefrom at distances'equal .to'said, common denominator whereby the 'fold lines divide said sheetintojia plurality of squares, said sheet also being provided with diagonal fold lines extendingfrom the corners of the sheet and with diagonal fold lines at angles of forty-five degrees (45?) from the intersection of said first mentioned-fold lines with the sheet edges, whereby each of said squares is divided by a pair of diagonal.fo1df;lines, the

sheet being foldable in either direction on all said fold lines, each of said squares being cutalong one of thediagonals thereof fromthe edge 0f;the sheet at least to the'center'of the respective square, said rectangular, sheet, whentpro'pe'rly folded, displaying upon its face exposed to view only one-fourth of the areaof 'anwentire'face thereofand when so properlyfolded'i'displaying' a representation of a 'knownobject. I

4. A picture puzzle comprising a square sheet provided with a pair of'medial fold lines parallel l v to the-sides ofthesheet dividing th l'sheet into rectangular quadrants, each of which: quadrants is provided with agfold line diagonally thereof I connecting the ends of. the medial-fold lines, each quadrant also being provided with a di'agonal fold line extending from the center of the sheet and extending at least to the center of the respective quadrant, each quadrant being out along one of the diagonal fold lines at least to the center of the quadrant, said rectangular sheet, when pro-perly folded, displaying upon its face exposed to view only one-fourth of the area of an entire face thereof and when so properly folded displaying a representation of a known object.
